LOS ANGELES (CBSLA.com) — The families of four of the six victims who were killed in a plane crash along with singer Jenni Rivera have filed a wrongful death lawsuit against the company that owned the plane, which crashed at more than 600 miles per hour.

Starwood Management LLC, which owned and operated the Learjet 25, has been named in the suit. The families are blaming the company for negligence in allowing the plane to take flight.

Records show the jet, built in 1969, was heavily damaged during a 2005 landing and then later cleared to fly by officials.

According to documents, Starwood Management also had one of its planes seized by the U.S. Drug Enforcement Administration in September.

Rivera’s company, Rivera Enterprises, has also been named in the suit.

“Likely, it was Rivera Enterprises that negotiated and arranged this flight, and that’s why Rivera Enterprises is a named entity,” attorney Paul Kiesel said.
